What is Twitter:
Website: Twitter.com
Twitter is the pioneer of microblogging. The idea is to have a really easy way to post short public messages. Twitter imposes a 140 character limit on "updates".
Ubiquitous input is another hallmark of Twitter (and to a lesser degree, microblogging in general). You can post a Twitter update using a Web form, email, instant message, various smartphone interfaces (iPhone, Blackberry, etc), downloadable desktop widgets, and more.
